The Clickable Table of Contents (C-TOC) enables you to access rapidly passages of audio interviews and other parts of audio data.
Why? Imagine, you have an interview with a length of 3 hours. Transcribe it, and you will have nearly hundred pages of dense text. You still do not know anything about the content unless you read the hundred pages..
A Clickable TOC offers a structure of the interview. Simply by looking at the outline you are informed what it is about. Furthermore, and more importantly, you can instantly access the segments. They are just a mouseclick away – no need of winding a tape recorder or searching in a digital audioplayer.
You can still transcribe the passages that are important for you or that you want to use as citation. Very often, there is no transcribing necessary whatsoever, because your have pieces of, say, half a minute or a minute length that are clearly assigned. You can easily refer to these segments. In Atlas.ti you can use them as basic elements for all future analysis. Another possibility to work with C-TOCs is to use the freely available software Winamp.
                             ATLAS.TI                                                            WINAMP

If you work with Atlas.ti you can tread the segments like “Quotations”. They are open to all kind of analysis.
Try it yourself. Save (right-click and “Save as..”) the two files below into a single folder and double-click “example.hpr”
When using a network-version of Atlas.ti, open the file from within the Programme.

Once the meaning-segments are cut out of the whole mp3-file, the freely available software Winamp shows all those segments as a Table of Content within its playlist.
Just download the zip-file below and un-zip it into a single folder. Then double-click the file “Playlist-Interview.m3u”
(Winamp can be downloaded

                 example.hpr     example.mp3              


Below is what you get in Atlas.ti and what you can access by mouse-click on each heading:
(first mm:ss indicates the start of the sequence, the second its length)
These segments can be treated as the basic meaningful pieces and be related to other quotations, codes, memos, comments etc. In Network views, for example, these relations can be shown and the elements can be accessed very easily by mouse-clicks.
